Agreed. Windows 11 will technically work with only 4GB of memory, but you can only have one or two programs open at a time and large web apps will be close to unusable. So quadrupling the memory was a good thing to do. I wouldn't have upgraded to Windows 11 if the customer hadn't agreed to the memory upgrade.
Speaking of resource intensive... i3wm is the opposite of that. I am enjoying it on my ThinkPad X270. I have to familiarize myself with it more. Sound is broken. I think the script didn't play well with Devuan. I should be able to fix it myself when I dedicate some time to it.
